I was wanting to find some day and night or light and dark/storm types of names. I found these ... I was thinking Thor for the copper boy because it means "thunder" and Nimbus for the white one because it is a type of cloud.

Other names I found for the white betta.They either mean white or light:Akiyo
Fintan
WittAbner
Dritan
Lux
Ori

I would really appreciate more name suggestions esp for the copper boy.
